Repellant to the point of loathsomeness
I am well aware that 12 O'Clock High is considered a masterpiece, but I find the character of Brig. Gen. Frank Savage (Gregory Peck) repellant to the point of loathsomeness, which undermines this otherwise well-made production.
Consider: Col. Keith Davenport (well-played by Gary Merrill) the commanding officer of a weary and battle-fatigued unit is removed from his command by Savage, who had been Davenport's friend. What did Davenport do wrong? In Savage's words: "He's a first rate guy who over-identifies with his men." As played by Gregory Peck, Savage is the most authoritarian martinet this side of Capt. Queeg. Unsurprisingly, every airman puts in for a transfer out of the unit. Aware that this will make him look bad, he conspires with his desk jockey ground officer Maj. Harry Stovall (Dean Jagger) to delay the transfers while he works to improve the units performance, and in doing so build cohesion and morale. When the Inspector General arrives, Savage is cleaning off his desk, sure that he will lose his command and be sent back to the Pentagon. But no, every man has cancelled his transfer request and Savage stays. I found this situation highly unlikely, considering that Savage had 1) relieved the popular Davenport of his command, 2) closed the Officer's club, 3) busted several of the airmen down a couple of ranks and 4) told them in a pep talk that they should think of themselves as dead men. I think it would be far more likely that they would have transferred out of the unit to get away from that neurotic mess of a general and that Savage would have been transferred to Washington. I was positively overjoyed when Savage finally broke down and was unable to carry out a mission.
What I find amazing is that several people in the comments said they used this film for leadership training (!) Maybe Savage's techniques work in the military, but anyone who tried to act that way in most modern organizations would find themselves in line at the unemployment office.
